Office.context.mailbox.makeEwsRequestAsync(request, function (asyncResult) {
  if (asyncResult.status == "failed") {
    console.log("Error" + asyncResult.error.message)
   // showMessage("Action failed with error: ");
  }
  else {
    console.log("Message Sent")
  // showMessage("Message sent!");
  }
});

In your SOAP request, you are calling the CreateAttachment EWS operation. This operation is not supported when running EWS in the context of an add-in. See this link for the full list of supported EWS operations: https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/web-services

Instead of using EWS, consider using REST/Microsoft Graph. We have documentation on that here: https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/use-rest-api.
